notice on the left a massive opening of the gallery, which on this point
doubles its width. This is also due to the fault in direction SW-NE. Here
starts the “Ramo dei Pipistrelli” translated to “The branch of the bats”, which
is possible to enter passing a narrow opening, soon leading to a room
consisting of a stalagmite pavement and usually inhabited by different families
of bats. Rimstones are also present, spectacular during rainy season.
